Yukihiro IKEDA


Yukihiro Ikeda is a Partner at Asamura Patent Office, p.c. and works on a range of patent-related work, including applications (patent applications for foreign countries, patent applications from abroad, and domestic patent applications, including PCT applications), appraisals, and invalidation trials.

His specialty fields are organic chemistry, inorganic chemistry, physical chemistry, pharmacology, biological chemistry, high polymer chemistry, petrochemistry, and other types of industrial chemistry.

Materials handled:
Pharmaceuticals (including pharmaceutical compositions, formulations, dosage forms, and natural medicine), immunizations, microbes, biogenetic materials, protein engineering materials, foods (sweets), fats, functional high polymers and resins (polymers capable of controlling electron functionality, separating films, light-sensitive films, and thermoplastic resins), organic and inorganic materials capable of controlling electron functionality, organic EL materials, electrode materials, lubricant agents, lubricant oils, paints, pigments, compacts, zeolite, hydrogel, cellulose, composite materials, transition metal oxides, compound semiconductors, catalytic agents, thin films, microparticles, crystals, and so on.

At university, Mr. Ikeda's undergraduate research was on finding the most stable position of a clathrate compound comprised of paracyclophane (host molecule) and an aromatic series guest molecule, using a program that he created to calculate the energy of intermolecular interactions. He also examined structural determination methods as alternatives for X-ray crystallographic analysis by comparing knowledge gained from nuclear magnetic resonance analysis, spectral fluorescence analysis, and other types of analysis.

During his time in the research laboratory of a general chemicals company, he joined the Research Project on Conducting Polymer Materials (R & D Projects of Basic Technology for Future Industries by the former Ministry of International Trade and Industry). There, he combined methods, including epitaxial polymerization, geometric isomer polymer synthesis, CVD, and Langmuir-Blodgett film deposition, focusing on materials, such as polyacetylene, polythiazyl, and polyacene, and researched the synthesis of these materials and performed physical properties evaluations. He also received patents in Japan and the US based on this research.
